The City Council on Tuesday adopted an ordinance implementing district-based elections in the city, the map establishing council district boundaries and election sequencing.

The first district-based election will be held in 2018.

The city’s consultant and residents have been submitting maps for council consideration for several months.

The majority of the council identified the consultant-drawn map as its preferred alternative in early March, despite opposition from some residents.

For weeks, residents questioned the council’s choice, raising concerns about the makeup and geography of the districts and whether they favored sitting council members.

The council tentatively approved the ordinance April 4. At that time, Councilmen Jon Harrison and Eddie Tejeda voted against the ordinance because they favored different maps.

While still in favor of a different map, Harrison voted in favor of the ordinance Tuesday.

“This was not my preferred map, but at this point it’s time to move along with this so I will be supporting the motion,” Harrison said.

Tejeda did not change his vote.

The map, known as Map 2B, places both Mayor Paul Foster and Councilman Jon Harrison in District 5, Mayor Pro Tem Paul Barich in District 2, Councilwoman Pat Gilbreath in District 4, Councilman Eddie Tejeda in District 1 and leaves an empty seat in District 3.

Districts 2, 3 and 5 on the ballot in November 2018, while districts 1 and 4 will be on the ballot in November 2020.
